Default Milling vs. thinnner gasket

I plan on milling my heads when I get them. Probably going to take off around .020.

Would going with a .045 cometic gasket and milling .010 be more effective then just milling them .020 and using the stock .054 gasket?

I guess what I am asking is if a thinner gasket will make more power than milling? Does it make a tighter quench angle?

any difference between the two?

thanks

Use the smaller gasket. This is assuming it will not cause piston to valve clearance issues. The smaller gasket will get you to a more optimized quench height than the .054 gasket. You want your quench to be somewhere in the .038 range if possible.

What he said. I'm going with 5.3 heads and then I'll measure P to V so I can order the thinnest gasket to optimize quench.
